Code:
 on *:TEXT:!rainbow:#: {
  if ($nick == bwttruman) {

    .timer 1 .01 msg # /color #ed1b24
    .timer 1 .02 describe #  RED
    .timer 1 .03 msg # /color #f7941d
    .timer 1 .04 describe #  ORANGE
    .timer 1 .05 msg # /color #f6ee27
    .timer 1 .06 describe # YELLOW
    .timer 1 .07 msg # /color #23b14d 
    .timer 1 .08 describe # GREEN
    .timer 1 .09 msg # /color #008fd5 
    .timer 1 .11 describe # BLUE
    .timer 1 .12 msg # /color #662e91
    .timer 1 .13 describe # PURPLE
  }
}
Here is what I did which is the colors and delays I want but I just want to be able to put whatever text I want in all of the messages after !rainbow
